Task Due Date

walterjs — Thu, 20 Jan 2011 16:40:40 GMT

I see that there is no property for a due date on the task as there was in jBPM 4. Are there any plans to add this in the near future or should this be handled differently?Usually, a user should be able to sort their tasks by priority and due date, but at the moment I can't see how to do this. Thank

Currently, there is nothing planned to add the due-date to the Tasks.
Sorting on priority however, is possible.


taskService.createTaskQuery().assignee("kermit").orderByTaskPriority().desc();

if you want it, please create a jira to add a duedate property to the task.

Thanks Tom, actually I'm happy to use something else if there is an alternative. How do you see this working and how is it defined in the BPMN?

It's not in the BPMN spec, and thats also the reason why we decided not to implement it in the past.

And there is no BPMN construct or concept that can be used as an alternative? If so, I guess the best option is to create an activiti:extension to the userTask, because I cannot see how you would do without it unless you store variables in the process context and display them in the item discriptions or model timers and escalations for each activity.

Well, I think that BPMN spec does not define any advanced human task handling like escalations, deadlines etc. Such things can be defined using WS-HumanTasks spec.

There is even special enumaration for such tasks in BPMN - implementation="HumanTaskWebService". We are considering using additional component implementing WS-HT for handling human tasks (this is how it's done in JBPM5 I believe), such as http://incubator.apache.org/hise/ (currently the development slowed down as few core developers left)

I've created this JIRA in the meantime: http://jira.codehaus.org/browse/ACT-564

Thanks

Is the setDueDate method missing from TaskService?

Walter,

You should just get the task, set the dueDate and save the task agian. In TaskListeners, you can just do delegateTask.setDueDate().

Thanks Frederik, that is what I'm doing at the moment. Just thought it strange that setPriority exists in the service, but setDueDate doesn't.

I see what you mean Not sure actually why it's there. Probabily a shorthand to a operation that is performed quite often…

Hello
With Activiti 5.10 change due date was possible with the following 2 lines

task.setDueDate(..)
ProcessEngines.getDefaultProcessEngine().getTaskService().save(task)

With Activiti 5.11 we have the following exception on the line 2 :

Caused by: org.activiti.engine.ActivitiOptimisticLockingException: TaskEntity[109811] was updated by another transaction concurrently

Any idea?
